These correspond to the exercises. Remember to load tidyverse.

library(tidyverse)

Make a simple point plot of Petal.Length on x and Petal.Width on y http://r-statistics.co/Complete-Ggplot2-Tutorial-Part1-With-R-Code.html

Change X axis label to “Width” and “Length”

Change the Y scale to 0 - 4 http://www.sthda.com/english/wiki/ggplot2-axis-scales-and-transformations

Try adding a different themes and find something you like https://www.datanovia.com/en/blog/ggplot-themes-gallery/

Add a colour on each dot to its respective Species http://www.sthda.com/english/wiki/ggplot2-colors-how-to-change-colors-automatically-and-manually

Change “ticks”/“breaks” on x axis to display: 1,2,3,4,5,6,7

Change Y axis to display: 0,1,2,3

Try to remove the legend completely https://stackoverflow.com/questions/35618260/remove-legend-ggplot-2-2

Add a linear regression model

Make the linear regression model fit through the entire data, not subdivided on Species

Same as before but make the regression line “slateblue” and remove standard error markings

Use the mtcars dataset. Write: data(mtcars) Create a violinplot with x = as.factor(cyl),y = displ

Add the rawdata as points

http://sape.inf.usi.ch/quick-reference/ggplot2/colour Make the violin edges dodgerblue1 and violin fill as tomato1, theme(classic), dots as magenta1 Make the violins transparent 50 %

Make the colors depend on aes cyl

Make the colors depend on aes as.factor(cyl)

Replace the violins with traditional boxplots See for example cheatsheet: https://rstudio.com/wp-content/uploads/2015/03/ggplot2-cheatsheet.pdf

Make a regular point plot with x = disp, y = mpg, color = factor(cyl), but facet_wrap the plot into am (automatic gear or not) http://www.cookbook-r.com/Graphs/Facets_(ggplot2)/

Do the same but make the size of each point depend on horsepower (hp)

Use the ChickWeight dataset: data(ChickWeight) Make a simple linegraph using x = time, y = weight

What went wrong here?

Make a simple linegraph using x = time, y = weight, group = Chick

Give each chick a different colour on the line

Give each chick a different colour on the line, but hide the ugly legend

Do the same graph but now make the color = Diet and show legend
